Title: Ventilating device in the window wall of buildings
Inventor: HACK GUENTER
IPC: F24F7/04
Filed: 1982-01-05
Abstract: The used ceiling air, cooling on the window pane and hence sinking here, leaves the room in the region of the windowsill through ventilation openings predominantly by way of interposed horizontal exhaust air headers. Parapet wall prefabricated elements have vertical air supply shafts which are predominantly heated by the ambient conditions without an energy supply. A chimney effect, and hence the automatic supply of preheated fresh air into the room, arises because of the heat. Predominantly for old buildings, the ventilating device consists of an outer housing attached to the window frame, with a mounting provided on it on which additional ventilating elements can be mounted as required by the users of the dwelling, for sound insulation, accommodation of a fan, or the like. Energy centres are accommodated laterally in the masonry. Parapets equipped predominantly with heat collectors are connected to the window as an integral element. The inlet and outlet openings for feed and exhaust air are laterally offset in the facade. Mounting jigs can at the same time be building features and have mountings for the attachment of the sub-structure for facade facings, of scaffoldings and facade accessories such as advertising, lighting, etc. <IMAGE>

Abstract: A powered hand tool is proposed which can be operated at two clockwise-rotation speeds and in anti-clockwise rotation by means of a combination (12 to 17, 64, 65) of a disengageable directional locking mechanism with a friction clutch. Two drive gears (4, 6) loosely mounted on a work spindle (3) are constantly in mesh with gears (36, 46) which are mounted on two separate back gear shafts (30, 44) and can be coupled alternately and in the opposite direction to the drive (43). The loosely mounted gear (6) which can be driven in clockwise rotation overlaps a collar (5) of the work spindle (3), which collar (5) accommodates rolling bodies (17) of a directional locking mechanism in recesses (14). Via these rolling bodies (17) serving as clamping bodies, this gear (6) is frictionally connected in clockwise rotation to the work spindle (3). Tongues (12, 13) projecting axially into the recesses (14) of the work spindle (3) engage in these recesses (14) on either side of the rolling body (17) as viewed in the peripheral direction. For the clockwise rotation of the work spindle (3), they press the rolling body (17) into the driving position relative to the collar (5) of the work spindle (3). During anti-clockwise rotation they move or hold the rolling body (17) in the released position. At the same time they drive the work spindle (3) anti-clockwise via a stop (65) at the end of each recess (14). <IMAGE>

Title: Optical turbidity meter
Inventor: BONFIG KARL WALTER PROF DR
IPC: G01N21/35
Filed: 1983-07-25
Abstract: In the practical design of optical turbidity meters, a quasi-parallel light beam is frequently introduced into the medium through a window. The scattered light is detected through a window arranged perpendicular to said window. The attenuation of the light is determined through a window situated parallel to and opposite the beam entry window, in order to compensate the light attenuation. This throws up the problem of the corruption of measured values by reflections and scattering at the vessel walls. By introducing a quasi-parallel beam at about 45 degrees to the window surface and measuring the radianted power transmitted by the medium through a window arranged at about 45 degrees to the optical axis of the beam, the beam is led away from the measurement volume and can be optically destroyed, as a result of which undesired reflections can be avoided. Furthermore, the sides of the windows towards the measurement medium become dirty to different degrees even after a short operating time. Even in the case of the measuring instruments which are suitable for measuring low turbidities and in which a contamination compensation is carried out only with regard to the light entry window, this results in a corruption of measured values. The use of two beams permits a formation of measured values independently of the degree of contamination, taking account of the avoidance of reflection. Moreover, the use of measurement probes which are open optically outwards due to the possibility of a ... Original abstract incomplete.
